Probe:	Crabp1 probe2
Probe preparation:	Antisense labelled with digoxigenin RNA
Visualized with:	Alkaline phosphatase

Structure	Level	Pattern	Image	Note
TS12: neural ectoderm	Present	Regionally restricted	1A	Expression is in the neuroepithelium caudal to the preotic sulcus. Based on comparison to Egr2 expression, Crabp1 is expressed in future rhombomere 4.

Structure	Level	Pattern	Image	Note
TS13: future hindbrain	Present	Regionally restricted	1C	Expression is in a wide stripe adjacent to the preotic sulcus.

Structure	Level	Pattern	Image	Note
TS13: future hindbrain	Present	Graded	1E	Expression is throughout the full thickness of the neuroepithelium. There are higher levels of expression in the dorsal half than in the ventral half.
TS13: rhombomere 5 neural crest	Present		1E

Structure	Level	Pattern	Image	Note
TS15: rhombomere 2	Weak		2A
TS15: rhombomere 4	Strong		2A
TS15: rhombomere 5	Strong		2A
TS15: rhombomere 6	Strong		2A
TS15: branchial arch mesenchyme derived from neural crest	Present		2A
TS15: future spinal cord	Present	Regionally restricted	2A	Expression is in the mesenchyme derived from the neural crest.
TS15: future midbrain	Present	Regionally restricted	2A	Expression is in the mesencephalic trigeminal neurons.

Structure	Level	Pattern	Image	Note
TS15: neural tube lateral wall	Present	Regionally restricted	2B	Expression is in the mantle layer in is a unique set of commisural neurons.

Structure	Level	Pattern	Image	Note
TS17: hindbrain	Present	Regionally restricted	2C	Expression is in the mesencephalic neurons of the trigeminal nerve. Expression extneds down the nerve to rhombomere 2 in the hindbrain.
TS17: midbrain	Present	Regionally restricted	2C	Expression is in the mesencephalic neurons of the trigeminal nerve. Expression extneds down the nerve to rhombomere 2 in the hindbrain.
